胎儿宫内缺氧是导致新生儿缺血缺氧性脑病、脑瘫的常见病因,也是围产儿死亡的主要原因之一,产前测胎儿宫内缺氧,对减低围产儿病死率,提高围产医学质量有重要意义。本文旨在探讨胎儿大脑中动脉(MCA)和肾动脉(RA)的血流指标对预测胎儿宫内缺氧的价值。1资料与方法1.1一般资料:选择晚期妊娠妇女356例,年龄23～35岁,平均27.2岁,孕龄35～40周,平均38.9周,均无妊娠 Fetal intrauterine hypoxia is a common cause of neonatal hypoxic-ischemic encephalopathy, cerebral palsy, but also one of the major causes of perinatal death, prenatal fetal intrauterine hypoxia, to reduce perinatal mortality and improve perinatal Medical quality is important. This article aims to investigate the fetal blood flow in the middle cerebral artery (MCA) and renal artery (RA) to predict the value of intrauterine hypoxia. 1 Materials and Methods 1.1 General Information: Select 356 cases of late pregnancy women, aged 23 to 35 years, mean 27.2 years, gestational age 35 to 40 weeks, an average of 38.9 weeks, no pregnancy
